<td>The InfiniBand p-key to use for this device. A value of -1 means to use the default p-key (aka "the p-key at index 0"). Otherwise, it is a 16-bit unsigned integer, whose high bit 0x8000 is set if it is a "full membership" p-key. The values 0 and 0x8000 are not allowed.

With the p-key set, the interface name is always "$parent.$p_key". Setting "connection.interface-name" to another name is not supported.

Note that kernel will internally always set the full membership bit, although the interface name does not reflect that. Usually the user would want to configure a full membership p-key with 0x8000 flag set.</td>

<tr>
<td><pre class="screen">parent</pre></td>
<td><pre class="screen">string</pre></td>
<td><pre class="screen"></pre></td>
<td>The interface name of the parent device of this device. Normally NULL, but if the "p_key" property is set, then you must specify the base device by setting either this property or "mac-address".</td>

<td><pre class="screen">transport-mode</pre></td>
<td><pre class="screen">string</pre></td>
<td><pre class="screen"></pre></td>
